클로로디이소프로필실란

용도Intramolecular hydrosilylation is also possible within β-diisopropylsilyloxy esters (13), constituting an exceptionally mild method for reducing ester groups to the aldehyde oxidation level (eq 4).The derivatives (13) may be synthesized from β-hydroxy esters (12) as described above for the analogous ketones. Treatment with fluoride ions (but not Lewis acids) induces hydride transfer to give alkoxysiladioxanes (14) in excellent yields (≥95%). Although usually performed in dichloromethane, the hydrosilylation may also be accomplished with ethyl acetate as solvent, providing strong evidence for intramolecularity.
